Windows RTM Enterprise edition leaks onto the Internet

Surely Microsoft expected this to happen and knew it was inevitable. The question is why did they choose to go this path and so carelessly distribute it? I mean they could have created special signed builds that tied the build to any one particular OEM or partner etc. That they could then hold accountable.

Was this all planned to maximize the proliferation of Windows 8 ? I have yet to download it and see what's up, any world on the activation protection if any? Considering this is the enterprise edition there might just be no protection.
